did a quick search (through N/A perf.), and i couldnt really find what i was looking for.

just been toying with the idea of an N/A RB30 powered skyline, possibly using a GTR throttle set-up.

feel free to call me a dreamer, as realistically, its going to be a bit before i can get it started.

but with that out of the way, does anyone know what would be involved in converting an RB30 to an ITB setup?

i remember seeing something about an adaptor plate quite some time ago, but i cant even recall who made them, let alone whether or not they'd suit an RB30.

for what im thinking the AFM would need to be deleted, so what ECU would you recomend to run it?

would i be able to get away with using a remap or piggy back? or would i need a programable unit?

what cam would you recomend? possibly a GTS cam?

so yeah, theres a few little questions, anything else you guys can think of/correct me on/flame me for?

thanks in advance guys.

dave.

I can get you an adaptor plate so that the GTR Throttles will bolt STRAIGHT up no messing around for around $700 delivered to your door.

Your looking at around another 150 - 250 for ITB's off the GTR, and then another 300ish to have trumpets made up if thats the way you wanted to go :blink:

Can supply all of the above and organise quotes if your genuinely interested, have done this to another mates RB30E for shits n giggles with bits n pieces we had lieing around. Induction noise is so hot, and he reckons it makes a big difference to the way the car drives... I couldnt really comment having never driven it though.

may have to get back to ya on that one.

but as i said, its still a while off, thats if i decide to go through with it anyways.

for now im just getting an idea of what id need if i do it.

PS. Deleting the AFM means you will need an ECU that supports MAP tuning im not too sure on whats available for RB30's though.

yeah, thats another issue im somewhat unsure of, im wondering if theres a piggy-back out there that would be able to handle, for the most part, the engine will be stock, the exception being the ITB's, extractors/exhaust and possibly a cam if the stocker isnt suitable. so a fully programmable, all the bells and whistles ECU seems a bit much.

Off the top of my head try ChipTorque in Nerang, QLD, pretty sure they offer a piggy back that might suit and save you some bucks on aftermarket management.

I'll try n get some pics of the adaptor I have at the moment (for an RB25 but gives you an idea) tonight if i can get a hold of the camera.

that would be sooo cool.. please please please do it... but if you do please do a twin cam conversion while your at it.

i think hks do an ITB and trumpet set up its purple and shiny ;)

ecu wise, i think you might want to look into a power fc d-jetro

  • 3 weeks later...

ive been looking at this also

their are two ways for compinsating for no afm

you could use a map sensor or you could also use a Throttle position sensor

throttle position sensor would be more expensive but easier to adapt.

where would you be taking the reading for the map sensor??

speaking from experience, MAP sensors find it hard to get a good solid reading at idle due to the lack of plenum associated with ITB's...

it is therefore a good idea to run a TPS based map only.

I suggest a microleb cough microtech

    • I bought the model back in Japan in Feb. I realised I could never build it, looked around for people who could build it, turns out there's some very skilled people out there that will make copies of 1:1 cars or near enough. I'm not really a photo guy... but people were dragging me in a group chat for the choice of bumper as someone else saw the car before it was finished as they are also a customer of that shop. I took the photo in the above post because I was pretty confident that the lip would work wonders for it. Here's some more in-progress and almost-done pics. It gives a good enough idea as to what the rear looks like!   I have also booked in a track day at the end of January. Lets all hope that is nothing but pure fun and games. If it's not pure fun and games, well, I've already got half an engine spare in the cupboard 
    • Well, do ya, punk? Seriously though, let's fu<king go! The colour and kit looks amazing on the car. Do you have any shots from the rear? I don't quite follow how the model came around. You bought the white kit and he modified it to match your car? Looks nuts either way!
    • So my car is finally back from paint! This took an absolutely insane amount of work and should get it's own build thread - but I didn't build it. It was completed by Troy @ https://scalekustoms.com.au/ I originally bought the AOSHIMA URAS Type R kit while I was in Japan, it's supposed to look like this when assembled: Now, I thought that was cool enough until I opened the box with Dismay, as there's no way I could possibly have completed it. The thing is 1/24 and has details down to the steering wheel horn button, which is a 2mm diameter sticker. I originally wondered if someone could make it at all, as is - But then things got a little carried away. It's worth noting that the model does not have an openable bonne, let alone engine bay, OR an openable boot. - Troy has worked wonders with 3D printer and presumably better eyes than I will ever have. My photos suck, so I will post up some of his in-progress ones he sent to me during the way. Unsuprisingly, he is very detailed. A lot of these are out of order. But he: 1) Made a LS engine and an engine bay appear out of thin air 2) Made the bonnet removable 3) Printed the rims I will buy in the future (or any rim you want) 4) Printed and added the wing that is going on 5) Tinted my back windows as this is what my car has IRL (privacy glass) 6) Added a licence plate. 7) Somehow did the interior 8) 3D Printed my actual seats 9) Made the exhaust under the car connect even though this is likely invisible. 10) Created a boot with my fking battery box, power steering reservoir, subwoofer and toolboxes back there. To say it's insane is an understatement. And I f**ked it all up because when I was re-mounting the wing (it broke in transit) I spilled glue everywhere and ripped paint up and Gregged the rear half of the car. Which about makes sense. Also, this arrived on the same day. Quite the change from: I spent 16 hours per day over the next 3 days pre-christmas putting the interior back together, mounting lip, fixing various bodykit problems with window mouldings, etc. and servicing, rebuilding my 370z brakes to go on the car 'soon', messing with heights to check clearances for new wheels, etc. I also had a foray into mounting wiper-mounted washer jets which was an absolute disaster. The bodyshop has welded (and painted) over the stock jet locations for reasons unknown to everybody (i.e they forgot) I also wanted to wire in the oil pressure sensor on Christmas Eve which was a BAD IDEA. You do not know terror like pulling your ECU apart, pinning in half-fitting pins that aren't the right ones, but trying anyway because it's Christmas eve, putting your ECU back together and having a no-start condition with a fuel pump not priming. Then you undo all your work and the fuel pump still doesn't prime. So after all that terror and horror and pain and tedious disassembly, the issue was the relay in the boot which seems to have died/stuck when I was turning the car off and on about 700 times testing shitty washer jets. I also re-wired the fuel pump power plug which fell apart in my hands. I am very happy I had 3 extra pre-made ones from a few posts/last Christmas's breakdown. https://bluewireautomotive.com/products/10-x-pcm-ecm-ecu-terminals I have put an order for these in, so I can actually add the pins to the ECU properly. The commodore ECU does not have the pins for Oil Pressure via ODB2. However the ECU can support it if you create the pins and wire them in. So for round two, and somehow attempting to route that into the engine bay through my impossible engine bay grommet is a fight for another day. It's 40C in Melbourne tomorrow, I am half tempted to drive the car with the aircon on to deliver presents to my partner's family and see if it helps with the overheating-on-40C-days-in-traffic-with-aircon-on-only issue that the vents were intended to solve. Do I feel lucky?
    • Yes, while being... strictly unnecessary. Tuning is a bit like quantum physics. You don't need to understand what Schroedinger's equation actually means. You just need to run the computation and accept the answers. With tuning, you just push page up/down until the exhaust tells you that you've got the fuel right. The VE can stay hidden behind the curtain like the Wizard of Oz and you'll never need to know what he looked like.
    • The second part yes, the first part about easy VE calculation is something I've seen a few people talk about online.
